This study explores the importance of scientific observation in primary education, highlighting how the use of observation sheets can facilitate the acquisition of knowledge and the development of students' observation skills. In the research, 153 second-grade students were divided into three experimental groups, each group observing a woody plant…

Social connections are crucial for today's middle and high school students. We address this social need through a 3-H Social and Emotional Learning (SEL) Cycle. Through the Three Sisters Garden activity presented here, we teach secondary school students about biodiversity and sustainability as we integrate the arts into STEM (STEAM). Students…

Plants and plant products are key to the survival of life on earth. Despite this fact, the significance of plant biochemistry is often underrepresented in science curricula. We designed an innovative laboratory activity to engage students in learning about the biochemical properties of natural polymers produced by plants. The focus of the hands-on…

Systems thinking is highly desirable for re-imagining chemistry education, which will help in the development of an integrated and sustainable approach that takes into account the interdependence of a system under study with other components of the ecosystem rather than practicing a fragmented approach. Thus, to develop a systems' perspective into…

The practice of RNA isolation in undergraduate experimental courses is rare because of the existence of robust, ubiquitous and stable ribonucleases. We reported here modifications to our original protocol for RNA isolation from plant tissues, including the recovery of nucleic acids by ethanol precipitation at 0 degrees C for 10 min and the…

Taking objects apart including old electronics, product packing, and living plants, helps children understand how things work. Documenting this "unbuilding" or "deconstructing" encourages children to first consider the entire object, then the parts, and finally, the purpose of the parts. This article provides a lesson based on…

The increasing urbanization and alienation from nature reduce children's opportunities to interact with plants and challenge teachers to devise educational practices that contribute to learning botany. This study presents the results of activities developed in a Brazilian school through explorations, drawings, dried and pressed specimens, and…

This practical lesson on greenhouses implements standards of the Next Generation Science Standards ("K-2 ETS I-2"; "K-LS1-1") and the preschool objectives from the Teaching Strategies GOLD. Teaching Strategies GOLD is an assessment tool available online and in print that can be used with any developmentally appropriate early…

Recent educational legislative acts and public debates in Sweden stress the importance of preschools providing playful and meaningful activities to enhance early experiences in environmental and natural science (e.g., Ministry of Education and Research, 2016). The present study investigates three 5-6 year old children making meaning of the concept…

In this article, students examined how and why plants work through in-depth investigations. They performed scientific inquiry through questioning, developed models, constructed explanations, and communicated information of the structure and function and system models of plants, and then engineered a representation of their understanding. The…

Elementary students should have opportunities to develop scientific models to reason and build understanding about how and why plants depend on relationships within an ecosystem for growth and survival. However, scientific modeling practices are rarely included within elementary science learning environments and disciplinary content is often…

African violet (genus "Saintpaulia") was identified as a particularly suitable genus for the study of specialised plant cells in the classroom using microscopes. The techniques described here involve simple preparation without staining. The cells and structures that can be investigated include: trichomes (hairs); stomata; guard cells and…

Terrariums have decorated the shelves and counters of biology offices and classrooms for centuries. Living organisms inspire students and teachers alike. These wonderful ecosystems allow for both experimentation and observation of living systems. Here, I outline a new approach to building classroom terrariums. Historically, terrariums have been…

Kindergartners have an energizing sense of wonder and an insatiable desire to learn about the world around them. For this reason, the study of ecosystems and how organisms interact within their environment is very exciting for these young learners. An appropriate place for young students to start constructing their own understanding of living and…

A national movement is underway to establish elementary school gardens, which can serve both academic and social purposes. These gardens can positively impact students' science achievement and provide the thematic and hands-on approach especially conducive to learning for students with disabilities. Garden-based learning (GBL) broadens the scope…
